IMPROVEMENT IN LAMPS.

Specification forming part of Letters Patent No. 38,453, dated May5,1863.

To all whom it may concern.-

Be it known that I, W. H. PrERoE, of Somerville, in the county ofMiddlesex and State of Massachusetts, have inventeda certain new anduseful Improvementin Glass Hand-Lamps; and I do hereby declare thefollowing to be a full and exact description thereof, reference beinghad to the accompanying drawings, and to the letters of reference markedthereon, like lettersin the figures indicating the same parts, and inwhich drawings.

Figure 1 is a perspective view of a glass hand-lamp having myimprovement represented thereon, and Fig. 2 is a vertical centralsection thereof.

Glass hand-lamps as heretofore consti ucted having their handlescomposed of the same vitreous material as the body of the lamp are mostliable to become useless by having their handles broken from accidentalcauses to which they are constantly subjected, particularly in,

packing and transportation.

The object of my invention is to obviate this objection to hand lamps,the bodies of which are composed of glass or other similar ware, and atthe same time produce alamp" he prime cost of which will not exceed thatof the glass hand lamp in ordinary use. To this end I form the body A ofthe lamp, of glass, of any desirable configuration, or in the form shownin the figures, and provided with an annular projection, b, as in Fig.2, around which to secure the screw-collar to the lamp body in the usualway by means of plaster-ofparis. The lamp-body A, as will be seen in thefigures,

. is manufactured in the first instance without the glass handleordinarily attached thereto; but in lieu thereof I supply the lamp witha handle, a, composed of metal and forming a part of the brass ormetallic collar D, applied to the top of the lamp. The collar D, Imakeof thin plate-metal, which, with the handle 0, may be cut with a diefrom a metallic sheet and afterward manipulatedinto the form shown inthe drawings and there be applied to the lamp-body in the condition of asingle connected piece of metal, or the collar D may be formed separatefrom the metal handle 0, the latter being riveted to the collar byrivets, or by soldering, or in any other appropriate manner, andthereupon united to the lamp-body, as indicated in the figures.

In Fig. 2, 6 indicates the plaster-of paris applied between the annularlip or projection 11 and the collar D to secure the latter in place uponthe lamp-body A.

A glass hand-lamp thus constructed is not only capable of beingmanufactured as a whole as cheap as the ordinary lamp with glasshandles, but is far more durable and not liable to be renderedcomparatively useless by the accidental breakage of the handle. It isapparent that if the collar D and handle 0 are made in separate piecesand then united as described, the handle 0 may in such case be composedof vulcanized gutta-percha, or a compound of gutta-percha andindia-rubber vulcanized, and still answer the purposes of my invention,in which case no unpleasant metallic smell will be imparted to the handof a person who may carry the lamp.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent of the United States, is-

1. Providing the metallic collar of a lamp with a projecting portion orcontinuation, which shall form the handle of the lamp, sub stantially asset forth.

2. The combination of a glass lamp-body, A, metallic collar D, andhandle, 0, substantially as set forth.

3. Fastening a metallic handle to a glass lamp by means of the collarand without puncturing the glass, substantially as set forth.
